NIGP 691: Power Transmission Equipment: Electrical, Mechanical, Air and Hydraulic

NIGP 691 Power Transmission Equipment: Electrical, Mechanical, Air and Hydraulic, Class, encompasses electrical parts, transmission infrastructure, switchgear systems, and related mechanical and hydraulic equipment that state and local agencies procure for utility operations, airport facilities, water reclamation plants, and municipal infrastructure. State and local buyers under this code range from county utilities and water districts to cities and airport authorities, with recent activity concentrated in Florida, New Jersey, Arizona, Connecticut, California, and New Mexico. Representative recent solicitations include Harris County Precinct 3's ITB for electrical parts and related items on an as-needed basis with responses due October 26, 2026; the City of Gallup, New Mexico's ITB for 115 kilovolt transmission line construction at the New Sunshine Substation, estimated at $673,000 with an anticipated award date of April 1, 2026; Okaloosa County, Florida's ITB for passenger boarding bridge preconditioned air units and ground power units at Destin–Fort Walton Beach Airport with bids due October 28, 2026; and the City of Dallas's request for bids to establish a three-year indefinite delivery/indefinite quantity service agreement for electrical switchgear repair services, with bids due October 2, 2026.

Geographic activity centers on Florida (Orlando water reclamation facility upgrades, utility vactor and pressure grouting services, asbestos cement force main replacement), New Jersey (prevailing wage projects including taxiway rehabilitation and industrial facility work), Arizona (Okaloosa County airport equipment, Tucson water system chemical-resistant parts), and the Southwest (New Mexico transmission line and California fuel station expansion). County utilities, municipal water departments, airport authorities, and city public works divisions dominate the issuing body mix. Set-asides include Davis-Bacon prevailing wage requirements on federally funded projects, DBE participation targets on FAA Airport Improvement Program work, Section 3 workforce requirements on HUD-assisted contracts, and state-level preferences in Arizona and Connecticut. The code sees activity across both small ($673,000 transmission line) and substantial ($5.9 million force main replacement) contract values, with many procurements structured as IFB or ITB vehicles for competitive bidding on fixed scopes and equipment specifications.
